“I received a recall letter from Porsche 11/29/17. As of 3/28/18 Porsche still hasn't sent parts to the dealerships to fix this problem. In turn this effects me because the Porsche dealerships will not purchase a call w/ a safety recall. Until this issue is fixed, I cannot sell my car. Porsche is costing me money every day that I am having to wait on this. Thank you.”
